Serial No. 631,598.

To all whom it may concern:

Be it known that we, WILLIAM. SPINK and JOSEPH M. BALTZ, both citizens of the United States, residing in 4the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Twisting-Machine, of which the following is a specification.

Qur invention consists of an improved reel or twisting machine for twisting two or more strands of yarn and reeling the same.

It further consists of improved means for positively driving the spindles and fliers.

It further consists of improved means'for controlling the speed of the spindles so as to drive the same with less speed when drawing strands from the ends of the cops than when drawing from `the-niiddles of the same.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

In machines for twisting a plurality of twisted strands of yarn from the mule and for then reeling it into hanks, it is of great importance that all of the several strands which are twisted into one yarn are twisted alike, as a strand which is twisted harder than the others is liable to kink in twisting and thus form a knot in the yarn, and it is also of importance that the twisted yarn receives the same twist at each flier, so that the several hanks of yarn will come out uni-v form. Heretofore the fliers and spindles in twisting machines have been driven by endless cords on pulleys, and the output from such machines has not been absolutely uniform in quality of twist, nor has it been pos sible to make the output vof each flier even, as some fliers, the cords of which were tight, would run faster than those in which the cords have slackened. The consequence of this would be, and is, that certain hanks of yarn come out satisfactory, while others will come out with knots and rough spots 1n the yarn, and also that some hanks will be iinished sooner than others, so that the entire set of spindles will have to be run while only a few fliers are in active operation.

lt is for the urpose of obviating these more or less obiectionable features, all of which are detrimental in an economical sense to the accomplishment of the greatest output with the least consumption of time and labor, that we have devised our present improvement.

"in the accompanying drawings we have illustrated one form of machine in which our invention may be embodied, but it is evident that the invention may be differently embodied without departing from the spirit of the same.

In the annexed drawings Figure 1 represents an end view of our improved twisting machine. Fig. 2 re resents an end view of the machine from t e end opposite that illustrated in Fig. 1. Fig. 3 represents a horizontal section on the line -a in Fig. 1, giving a top plan view of the lower part of the machine. F ig. 4 represents a front elevation of the machine, with certain portions of the driving mechanism brokenaway and removed. Fig. 5 represents a sectional detail view of the pulleys and sprocket wheels of the driving mechanism.' Fig.` 6 represents a plan view on an enlarged scale, in detached position.

Similar numerals of reference corresponding parts in the figures.

Referring to the drawings: the machine has two end-frames, 1, upon which are supported afront rail, 2, a spindle rail, 3, and a cop-rail, 4:. A shaft, 5, is journaled in bracket-bearings, 6, at one end of the machine .and has a drive-pulley, 7 secured upon it, which derives rotary motion from a belt, 8, or from other suitable driving source of power. A pulley, 9, is loose upon the shaft, alongside of the fast pulley;` and still another pulley, 10, is loose upon the shaft and alongside of said former pulley. A belt-shifter, l1, is provided to shift the belt upon either of the three pulle s". A sprocket-wheel, 12, is secured upon t e hub of the inner, loose pulley, 9, and a sprocketchain, 13, asses around said Wheel and a sprocket-w ieel, 14, of larger diameter, joui-- naled upon a short countershaft, 15, projecting from the end-frame and parallel to the drive shaft, A sprocket wheel, 16, of smaller diameter is secured to said largediameter wheel 14 and also journaled upon said shaft, and a sprocket-chain, 17, passes around said small wheel and around a sprocket-wheel, 18, secured upon the driveshaft. A splrocket-wheel, 19, is secured upon the drive-s aft, and a sprocket-chain, 20, passes around said wheel and around a sprocket-wheel, 21, of smaller diameter, which is secured upon a shaft, 22, journaled in a bracket, 23, upon the end-frame. Said shaft has a bevel-wheel, '24, secured upon its end, which meshes with a bevel-wheel, 25,

upon the lower-end of a shaft, 26, journaled in a bracket, 27, upon the end-frame and carrying a sprocket-wheel, 28, upon its upper end. Said latter sprocket-wheel is in a plane above the spindle-rail and a sprocketchain, 29, passes around said wheel and around a sprocket-wheel 30, at the opposite end of the spindle-rail and having its shaft, 31, journaled in a bracket, 32, upon the endframe there. The sprocket-chain is supported upon rollers, 33, mounted upon the spindle-rail, and engages small sprocket-wheels, 34, upon main-spindles, 35, of flier-frames, 36, which spindles are stepped in step-bearings, 37, upon the spindle-rail and journaled in bearingsl in an upper spindle-rail, 38, above the spindle-rail. v

Each flier-frame consists of two spiders, 39 and 40, upon the main-spindle, having radiating arms in which cop-spindles, 41, are respectively stepped and journaled.. Each cop-spindle has a pinion, 42, upon 1t, and sald pinions mesh with an lnternal cog-gear, 43, supported upon the upper spindle-rail. The upper ends of the main-spindles carry radiatlng arms,44, each formed with two guide-eyes, 45, and all registering with the cop-spindles. Yarn-guides, 46, are supported above the dier-frames in brackets, 47, and each guide corresponding to and registering with Va iiier-frame. 'Each yarn asses from the upper yarn-guide to a guide-eye, 48, upon a reciprocating traverse-bar, 49, sliding in bearings upon the front-edge of the front-rail` of the machine. A reel, 50, has its shaft, 51, journaled in bearings, 52 and 53, in the end-frames of the machine, and the yarn is passed from the eyes upon the traverse-bar to said reel and is wound in hanks upon the same. A pinion, 54, upon the reel-shaft meshes with a inion, 55, upon a stub-shaft upon the endrame, and said latter pinion has a wrist-pin, 56, upon its face, upon which in the lower end of a pitman, 57, is pivote The upper end of said pitman is pivotally connected to a bellcrank, 58,' fulcrumed upon the front or' the frame, and the other arm of said bell-crank has pivoted to it one end of a connecting rod, 58X, the other end of which is pivoted to the traverse-bar. A sprocket-Wheel, 59, is loose upon the reel-shaft, and a half-clutch, 60 is formed upon the inner face of said sprocket- Wheel and engages a half-clutch, '61, sliding upon and rotating with the reel-shaft. p latter half-clutch has a circumferentially grooved hub, 62, which is engaged by studs, 63, in a frame, 61, encircling said hub and formed in an a-rm, 65, fulcrumed at its lower end upon the frame and having its upper and pivotally connected to a bar, 66, sliding beneath the front-rail. Said bar has, at suitable distances apart, pairs of forwardlyrojecting blocks, 67, between which the ower arms of shifting levers, 68, fulcrurned Said upon the front edge 'of` the ront-raiL-engage, so that the bar may be shifted and the clutch operated from. several points along the front of the machine. A sprocket-chain, 69, passes around the sprocket-wheel 59 upon the reel-shaft, and passes around a small sprocket-wheel, 70, upon a 4stub-shaft, 71, projecting from the end-frame, and a sprocket-Wheel, 72, of larger diameter is secured to said small wheel and also journaled upon said `stub-shaft. A chain, 73, passes around said larger wheel and around a small sprocket-wheel,74, upon the drive-shaft, so that the reel may thus be driven from said shaft. The bearing 52 for the reel-shaft is formed in the center of a circular frame, 7 5, having one side open, and revolubly mounted in a semicircular support, 76, in the endframe, so that the nished banks, 77, may be removed from the reel at that end.

In practice, cops, 7 8, of yarn from the mule are placed upon the spindles and the yarn is threaded through the several guide- Y ioI slow motion to the Hier-frames and spindles through the sprocket-wheels and chains, so that the yarn will not be pulled oii the cop and tangled. Vhen the work has advanced so far that yarn is unwound from the thicker portions of t-he cops, fast speed is resumed by shifting the belt on to the outer and fast pulley, and such speed is maintained until the cops are nearly empty, when slow speed is again used. The flier-frames and spindles being` positively driven by cogged -gearing and sprocket-chains and wheels, said frames llO and spindles will all be driven at an absolutely uniform rate of speed, so that all the banks of yarn wound upon the reel will be of uniform twist. obtain where belt, cord, or other frictional drive is employed. As, the cops are all wound with substantially the same quantity of yarn, all fliers inthe machine will finish their work at substantially the same vtime and all banks will be finished at about the same time.

By providing the device for driving the fiiers at slow speed at thev beginning and ending of unwinding the yarn from the cops, waste will be prevented from stripping and tanglng the yarn at the ends of the cops, and waste will also be prevented by driving the fiiers at uniform speed and This uniformity cannotV wool-spinning machinery.

The clutch-mechanism upon the reel-shaft is provided for the purpose of disconnecting the reelfrom the remainder of the machine, so that in removing the hanks, the operator shall not be obliged to operate all oi the parts of t-he machine, but can revolve the reel freely and Without undue exertion.

As all of vt-he several driving mechanisms are positively driven and co-act in unison, it is necessary to have manual control by the machine operator of the s eed-changing devices for the fliers, spindles and reel, that such control may be exercised when the Winding from theends of the cops is started and for this purpose we have provider manual control of the speed-changing mechanism, as automatic control for such pur ose is not practical.
